To all whom t may concern:

Be it known that I, SIDNEY MOORE, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia. and State of Pennsylvania, have invented a certain new and useful Automatic Filling-Lock, of which the following is a specification, reference b e-l ing had therein to the accompanying draw-` ings.

1o This invention relates to looms; and the object in View is to provide an automatic filling-lock arranged contiguous to the raceway and adapted t`o automatically separate and successively raise and lower the fillingthreads at proper intervals during the move- The object of the invention is to provide.

simple and reliable mechanism adapted to be e5 applied to looms of ordinary construction arranged at or near the end 4of the lay and adf jacent to the tier of drop shuttle-boxes adapt-` ed to raise and lower and securely hold the different lling-threads above or beneath the 3o raceway as the different-shuttles are thrown back and forth, the mechanism comprising a series of fingers which are automatically moved upward or downward as the drop shuttle-boxes are Vraised and lowered, the op- 5 erating mechanism for the fingers being controlled by the movements of the drop shuttleboXes.

lVith the above and other objects in view, which will be more fully understood as the 4o nature of the invention is set forth, the invention consists in the novel construction, combination, and arrangement hereinafter fully set forth, illustrated, and claimed.

In the accompanying drawings, Figure 1 is a side elevation of one end of the lay of a loom, showing the invention applied thereto. Fig. 2 is an enlarged detail perspective view of the automatic iilling-lock.' Fig. 3 is a plan view of the same. Fig. i is a detail perspec- 5o tive view showing the operative connection between the drop shuttle-boxes and the arm of the operating-lever. Fig. 5 is a detail horizontal section showing the manner of adjustY ing the fulcrum of the operating-lever.

Similar numerals of reference designate corresponding parts in all figures of the drawings.

In the drawings I have illustrated one end of the lay of a loom, in which 1 designates a portion of a loom side; 2, the arch; 3, the lay; 6o 4, the lay end casting, and 5 a tier of drop shuttle-boxes.

6 designates the lay-sword, which is connected at its lower end to the rocker-shaft 7, said rocker-shaft having connected thereto the rocker-iron S.

9 designates the shuttle-box lifter-rod, supported at its lower end by the rocker-'iron and encircled by a coiled spring 10, the lifterrod having at its upper end the usual lifter- 7o forkll, ext-ending downward from the drop shuttle-boxes 5.

12 designates the box-chain, which is connected at its lower end to the lifter-rod 9 and passes over a sheave 13, supported on a bracket connected with the lay end casting, said chain forming the means for automatically operating the shuttle-boxes in a manner well understood by those familiar with the art to which this invention appertains. 8o

In carrying out the present invention I provide a supporting-plate 14., which is secured in any convenient manner to a standard 15, extending upward at one side of the raceplate 16, which forms the bott-oni of the race- V way over which the shuttles move. At a suitable point'the race-plate is provided with a transverse depression 17, and above said depression is arranged a bearing-plate 18, which may be supported at one end by a post 9o or standard 19, extending upward from the race-plate, and at its opposite end by horizontally-extending arm or brace 20, having a slotted and adjustable connection at 2l with the supporting-plate 14.

Extending laterally and outward from the plate 14 is a stud 22, forming a common fulcrum for aseries of oscillatory arms 23, three of such arms being shown, and each arm being provided with a terminal finger 24, all of roo said fingers extending at right angles to their respective arms and being arranged in paralle'l relation to each other, as clearly shown in Fig. 2. The lingers when in their lowest positions are adapted to be received in the depression 17in the race-plate, and when elevated they are received in parallel grooves 25 in the lower surface of the bearing-plate 18. The said lower surface of the bearing-plate 18 and also the grooves 25 are lined with leather, cloth, or other textile or similar material, as shown at 26, in order to obtain the necessary frictional hold on the fillingthreads and prevent them from beinginju red and severed when held lirmlyagainst the bearing-plate by the fingers 24.

Each of the levers 23 is provided at the opposite side of its fulcrum with a heel extension 27, with which one of the engaging portions of an operating-lever 28 engages. Said lever is fulcrumed on a stud 29, which is connected with the supporting-plate 14. At one end and on one side of its fulcrnm the lever 28 is provided with stepped engaging portions 30, which are adapted to successively come in contact with theheel extensions of the oscillatory arms 23 for depressing said heel extensions and raising the fingers 24 into contact with the bearing-plate 18, at the same time lifting the filling-threads supported by said fingers. At this point it may be stated that any number of fingers may be employed, according to the number of filling-threads, and that one less finger is employed than the number of filling-threads. It will be noted that the steps 30 of the lever are arranged in the same planes with the heel extensions 27, so that each engaging portion can only operate upon its respective arm 23. ther be seen that the outer surface 3l of the operating-lever is concentric to the axis of movement thereof and that each of the heel extensions is provided with a concaved dwellsurface 32, so that after an engaging portion of the lever has acted upon its respective arm 23 and raised the finger 24 thereof the concentric outer surface 3l of the lever will bear and move against the dwell-surface 32, thus holding the arm 23 stationary with the finger 24, holding one of the filling-threads against the bearing-plate. It will also be seen that by providing the lever with the stepped engaging portions there is a dwell between the successive movements of the several fingers, giving time for the shuttle-box to move back and forth.

The fulcrum-stud 29 is made adjustable with respect to the supporting-plate 14, as shown in the detail sectional view Fig. 5, in which it will be seen that the lever is provided wit-h the sleeve 33, through which the stud passes, and the plate 14 is provided with a slot 34 to receive the reduced inner end or shank 35 ofthe stud, the stud being provided with a shoulder 36 to obviate any binding of the operating-lever 28, which shoulder bears against the plate 14. The fulcrum-stud 29 It will furv ception of the may be adjusted toward and away from the stud 22, on which the arms 23 are mounted, by moving the stud lengthwise of the slot 34, and the adjustment may be fixed by means of the nut 37, which bears against the 4inner side of the plate 14. By providing the adjustable fulcrum-stud the throw of the oscillatory arms and the fingers carried thereby may be regulated to agree with the distance between the race-plate and the bearing-plate.

The lever 28 is also provided with an oper? ating-arm 38, which is pivotally connected thereto at 39 and adjustable relatively to the lever by means of a clam ping-screw 40, which passes through a curved slot 41 in the lever 28 and engages a threaded opening in the operating-arms 38. The object of this adjustment is to adapt the operating-arm to the position of a swivel-head 42, which is carried by a bracket or attaching-plate 43, adapted to be secured to one of the drop shuttle-boxes, and preferably the upper one thereof, as shown in Figs. 1 and 4. The head 42 has a swiveled connection with the bracket 43 and is provided with a slot or opening 44, in which the operating-arm 38 is slidingly received, whereby as-tlie drop shuttle-boxes are raised and lowered the operating-arm 38 is caused to move in a corresponding direction, thus rocking the operating-lever and causing it to successively actuate the oscillatory arms 23, with the result that the fingers 24 are moved upward and downward one after the other for the purpose of separating the fillingthreads carried thereby and moving said threads alternately upward and downward, so as to hold them under tension and out of the way of the traveling shuttle. In this way all of the threads are held under tension and out of the path of the shuttle, with the exparticular thread upon which the shuttle is operating, thus obviating the danger4 ot' the shuttle becoming entangled with the several filling-threads and drawing the same into the cloth.

The device hereinabove described may be placed on all kinds of looms for textile weaving and may be employed in connection with any number ot' boxes, circular or otherwise. The use of the automatic lilling-lock hereinabove described will be productive of cleaner and more even cloth, will obviate a large amount of filling-cutting, and will prevent the dirt spots, com monly called shuttle-marks, by reason of the filling being heldl tightly by the fingers and the shuttle prevented from coming in contact therewith. By the use of this illinglock the manufacturer can do away with the steam-box commonly used to take the curl out of the lling, enabling him to put any amount of twist in the filling without danger of the filling being drawn into the cloth to the injury thereof. It is also productive of more even selvage and will eect a great saving in the burling of the cloth. The cloth produced will also be more uniform in width, and a considerable saving in mate IOO csv/13s rial will be effected by preventing the filling strands or threads from becoming looped and worked into the cloth.

I do not desire to be limited to the exact details of construction hereinabove set forth, and accordingly reserve the right to change, modify, or vary the construction within the scope of this invention.

Having thus described the invention, what I claim as new, and desire to secure by Letters l.
